WRENCH.

SPECIFICATION forming part of Letters Patent No. 311,202, dated January27, 1885.

' Application filed April 14, 1884. (No model.)

10 all whom, it may concern.-

Be it known that 1, WASHINGTON LAFAY-.

ETTE PARKER, a citizen of the United States, residing at Spartanburg, inthe county of Spartanburg, State of South Carolina, have invented a newand useful WVrench, of which the following is a specification, referencebeing had to the accompanying drawings.

struction and combinations of parts hereinafter fully described, andpointed out in the claims.

In the drawings, Figure l is a perspective view of a wrench embodying myinvention. Fig. 2 is a side view of the same, showing the wrenchadjusted in position for operation, and Fig. 3 is a detail view inperspective of the sliding sleeve or collar and the jaw or hook pivotedthereto, a portion being broken away to show the construction moreclearly.

In the accompanying drawings, in which like letters indicatecorresponding parts in the several figures, A represents the handle,which is formed upon its lower edge, a short distance from the forwardend thereof, with a series of teeth, a, which incline in a rearwarddirection. The end of this handle A is out off diagonally, as shown, andsaid out off end is provided with serrations b, adapted to bear againstthe object to be operated upon, to prevent any liability of slipping.

B representsa sliding sleeve or collar, which consists-of the parallelsides 0, the lower end of said sides being connected by means of atransverse bar, d, having an inclined or oblique face, said bar engagingthe teeth upon the under side of the handle 0, to prevent said collarfrom slipping when the wrench is being operated. It also serves toprevent the disengagement of the said collar or sleeve from the handle.Between the other ends of the sides cis pivoted, by means of atransverse bolt, 0, the

jaw or hook C, said hook orjaw Ohaving its forward or front end turnedinwardly to form a I tooth or projection, D, which, in connection withthe serrated end of the handle, is adapted to grasp and firmly hold theobject to be op erated upon, the crossbar (1 being beveled in order thatit may more firmly engage the notches or teeth upon the under or loweredge of the handle A.

' Between the sides of the sliding collar or sleeve B, adjacent to thepoint at which the jaw or hook O is pivoted, is provided a transversebar, E, which is adapted to limit the vertical movement of the saidcollar upon the handle, and also to prevent the contact of the handlewith said pivoted jaw O, as would otherwise bethe case. The pivoted jawis, however, .allowed ample room, and its free working is not interferedwith by said bar. Upon the forward end of the collar is pro-. vided araised portion, f, which forms shoulders, thus preventing anypossibility of the sliding sleeve slipping from the handle.

In the operation of the above-described wrench the hook or jaw Oisplaced over or around the pipe or other object to be turned, the leveror handle Abrought to bear against the opposite side, the adjustmentbeing made by slipping or sliding the sleeve B along the handle A andlodging it in any notch that will give the grip. \Nhen power or leverageis exerted, the handle will tighten on the pipe or other object, and thesame may then be readily turned.

It will be seen from the above description that a wrench constructed inaccordance with my invention is simple in its construction; that theparts are not liable to become disarranged or out of working order; thatthe adjustment of the wrench upon the pipe may be almost instantaneouslyobtained; that it affords great power; that it may be manufactured andsupplied at a comparatively slight cost, and that it is also light anddurable.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a pipe-wrench, the combination, with a suitable handle, A, formed onone of its edges handle, the forward end of the'hook or jaw extendingaround thefront end of the handle, the action of the hook or jaw drawingthe 10 sleeve or collar in an inclined position onthe handle to causethe bar d to engage with the teeth more firmly, as and for thepurpose'set forth.

In testimony that I claim the foregoing as my own Ihave hereto affixedmy signature in i5 presence of two witnesses.
